I'm stuck with this join. I have these tables:
This database tracks reports found online. Each report has the ability to be featured if needed. If the report is featured, it gets entered into the table. If an existing featured report is edited to be not featured anymore, the record in the featured table gets deleted. The website I'm creating will pull the most recent featured record and display all relevant info for that report.
The website will also sort and display the reports by category and year.
A report can have a pdf link, a web link, or both.
The problem I'm having is getting a result set that has all the info of the report, the pdf and web links IF they exist, and the featured id IF that exists.
SELECT rpt.title, rpt.source, rpt.imgURL, rpt.imgAlt, rpt.description, rpt.month, rpt.year, cat.ccr_catDesc, pdf.pdfURL, web.webURL FROM ccr_reports as rpt, ccr_pdf as pdf, ccr_web as web, ccr_category as cat WHERE rpt.ccr_rptID = pdf.ccr_rptID AND web.ccr_rptID = rpt.ccr_rptID AND rpt.categoryID = cat.ccr_catID AND rpt.ccr_rptID = strPassedID
Where "strPassedID" is the record ID passed in from the site.
This only worked if there was a pdf and a web record listed in the tables. If a report is missing either a pdf or web link, the result set is nothing.
Is there a way to conditionally include record data when querying a database? or perhaps a way to display a null for that field but still return other relevant data?
Please help me. Any bit of info would be greatly appreciated.
